God of War: Chains of Olympus is an action-adventure hack and slash video game developed by Ready at Dawn, and published by Sony Computer Entertainment (SCE). It was first released for the PlayStation Portable (PSP) handheld console on March 4, 2008. The game is the fourth installment in the God of War series, the second chronologically, and a prequel to the original God of War. It is loosely based on Greek mythology and set in ancient Greece, with vengeance as its central motif. The player controls Kratos, a Spartan warrior who serves the Olympian gods. Kratos is guided by the goddess Athena, who instructs him to find the Sun God Helios, as the Dream God Morpheus has caused many of the gods to slumber in Helios' absence. With the power of the Sun and the aid of the Titan Atlas, Morpheus and the Queen of the Underworld Persephone intend to destroy the Pillar of the World and in turn Olympus.
